Ways of reducing the weight of our cars
fuscobal:
Just finished installing the A3 reinforcement bar and let me tell you Bruce, your weight difference estimation is waaay off :))) The difference between the 2 of them is only 1.5Kg (7.1 for the steel one and 5.6 for the aluminium). After removing one of the ''lips'' of the S3 bar, because it was touching my Forge twintercooler, I gained anothe 0.3Kg so that made a total saving of 1.8Kg (far less than the 10Kg you estimated). The shape difference of the 2 bars is also quite difference and you need to add the bracket on the middle and you need to fabricate some others at the 2 ends of the bar. I improvised all these for the moment because the shops were closed and I didn't find any universal iron to finish the job properly. I said I should finish it once started but wouldn't recommend anyone to do it because the weight saving is too small !

:surprised:
Pardon me, I really thought there would be more difference !!
:ashamed: :ashamed: :ashamed:
Gladly you did a great job. I guess it must have been a hard one as well.
:confused:

Replacing the bars takes like 2 hours including trimming the A3 one but you need another 1-2 hours to fabricate new brackets in order to reinforce the whole assembly comprising the radiators and the FMIC. As it is now, the assembly is a little loose if you grab it with your hand and shake it. I will buy some universal iron and custom make the brackets ! Next on the list is the battery : Odyssey or Braille wich should save me like 15Kg !

Now having the bar is on your GTI you might like to drill it with
large holes on all four sides to save quite a bit more weight?
I still worry about my self being mistaken so much. :ashamed:
Carrera2RS:
Great write up. Thanks heaps for doing this exercise, shame the saving is minimal :ashamed:
I think I will concentrate on settings to dial out understeer and improve turn in and balance. tbh given the weight over the front axle I should be very pleased !
